Be it known that I, GEORGE-W. WEIss, af.

of New York, in the county of Kings and State of New York, have inventedcertain Fans, tion. .V .j

This invention relates to. powerfans and more particularly to'thatelassof vpower fans -of which the ollowing is aspecicafor the benefit of theoperators thereof the provide a fan of the class referred to that wil becheap in pable of being readily adjusted to direct the With such objectin View, my invention y detail and pointed out inthe Referring now totheaccompanying drawings forming part of this sv eciication; Figure 1 is arear Vside view o a fan embodyative engagement with the fly-Wheel of ais an end view of the parts shown inFig. 1, looking from the left. Figs.3 and 4 are front and side views, respectively, of a modifiedv form ofthe invention. 1

A- fan embodying my invention may be located upon any suitable supportand be` actuated from any suitable motive power, but the same is hereinshown as being located upon a sewing machine table, indicated at 2, andas bein adapted .to be actuated from the ily-wheel of a sewing machine,indicated at 3.

The fan preferably comprises a supporting parts of the an are supportedand which is adaptedto'be fixedl secured at its base to the table 2 bysuitab e fastening means,- such as the screws 5. At its u perend thestandard 4 is provided with aL aterally projecting arm 6 having avertical perforation in which issu ported a verticallyand rotatably ad-'Specicationiof Letters Patent. v.pplnmtimn mea my s, 190e. semi No.315,383.

justa e stem 7 having at its 'upper end a Patented June 2, 190s.

substantially U-shaped bracket 8 in which is journaled a shaft 9 havingiixedly attached thereto a fan 10. With such described adj ustable'connection between the stem l7 of the fan-carrying bracket andthestandard 4the 'fan 10 may be adjusted vertically, and also angularly 1na horlz'ontal plane, to direct the current of air created thereby` in adesired direction with respect tothe operator of the machine or othererson using the same, and after the fan has een adjusted to a desiredposition, it will then'be held stationary in Such position by suitable`fastening means, such as the set-screw 12 in the standard '4 engagngthe stem 7. A

The adjustment of the fan as described is sufficient under all ordinaryconditions, but in some instances it may be desirable to have an angularadjustment of the same in a verl ticalplane, and in order to provide forthis I form the'stem, as shown inr Figs. 3 and 4,

with an extension 14 having aliorizontally arran ed end 15 upon lwhich afan-shaft-car oscillating movement in a vertical plane, the

lsaid bracket being adapted `to be held instationary'adjusted positionrelative to its'su porting stem by means of a set-screw 17 j! As a meansfor driving the fan, I have joug.'- naled a shaft 20 in a bracket 21Amounted on the standard, below its upper end, which shaft isprovidedwith a friction-disk'or pulley 22 for en agement with a suitable motor,

such as the y-wheel 3 of a scanne-machine,-

ryingracket 16 is mounted to be capable of and is belted' to thefan-carrying shaft 9lby a belt 23 passing over grooved belt-pulleys -24located on the respective shafts as shown.Jv y The said belt 23 may bemade of elastic material if desired so as to be self-adjustin to anychange in the vertical position of the a ,carr mg shaft 9, butordlnarilyI prefer to a non-elastic belt, which event I emp o rovi e a meansforautomatically controling' the slack in the belt u on' any changempositionvof the f an being e ected, such meansy as herein showncomprls'ing a s ring arm 26 attached at one end to the brac ,et.21, asat 27 andat its opposite end carrying a pulley 'ibo 28 for engagementwith the belt'at a `point intermediate of thebelt-pulleys 24 as shown.It will -De seen that'by this structure, the

vbelt is always maintained taut as the pulleys i,

28 and 22are in substantiallyfixed relation lto each other, lso thatmovement'of the'pul-fk atiye `have pivoted the bracket 21 to thestandard lley 22, when. adjusted, in no way tends to slacken the belt,as would be the case were the pulley 28 secured to the standard or insome other position permitting substantial relative movement between thepulleys.

' In order that the friction-disk or pulley 22 may be readily moved toand from an o erosition of contact with the fly-w reel 3 .of't emachinewhereby the fan will be" caused to either operate or be stationary, I

at and located an adjusting-screw 31 in v the standard in a position tohave the bracket stated.

yieldingly, held against one end thereof by means of a spring, asindicated at 32. With this arrangement and combination of parts, a mereturning of the screw 81 in the proper direction will cause thefriction-disk 22 to be moved either to or from a position of engagementwith the fly-wheel 3 for the purpose 'What I claim is: 1. A power fancomprising a supporting standard, a bracket rotatably mounted thereonfor adjustment in a horizontal plane, a fan operating shaft journaled onsaid bracket, a second, bracket pivotally supported on the .-standard, adriving shaft journaled on said bracket and geared to the fan operatingshaft, means on said driving shaft to receive rot/atory movement, aspring to move said pivoted bracket in one direction, and means to moveitin another direction against the force j o f the spring.

, spring, and a spring actuated pulley mounted Aon said second bracketand engaging said belt to maintain automatically the same tautirrespective of the adjustment of said bracket.

3. A power fan comprising a rsupporting standard, a fan carrying shaftjournaled at the upper portion thereof and means whereby it isadjustable with relation thereto into different angular positions, abracket movably mounted on the standard at a point belwsaidshaft'themovement of said bracket being independent of the adjustment ofthe fan carrying shaft, a driving shaft journaled on said bracket andgeared to drive the fan carrying shaft, a spring to move the bracket inone direction, and means to move it in another direction against theforce of the spring.

4. In a power fan, a standard, a bracket rotatably mounted thereon foradjustment in a horizontal plane, a horizontal extension to saidbracket, a sleeve mounted on said eX- tension, a fan vshaft journaled onthe sleeve, said sleeve being rotatable about said extension to permitadjustment of the fan shaft in a vertical plane, and means for securingsaid sleeve in adjusted position.

5. A power fan, comprising a supporting standard, a rotary shaft havinga fan attached thereto, abracket carrying said shaft and having anadjustable connection with the standard said connection permittingadjustment independent of the fan carrying shaft, a bracket pivotallyconnected to the standard, a driving shaft carried by said bracket andhaving a pulley for engagement with an actuating part, a beltoperatively connecting said driving shaft with the fancarrying shaft,and means comprising a spring and an adjustable screw for moving thesaid bracket to shift the pulley of the supported driving shaft to andfrom an operative position for engagement with its actuating part.
